Library mission completed, Karyn returned to Jon’s house to find him and Zoe still embroiled in an argument about whether she could keep the larger breasts she’d picked up at the mall earlier. “You can borrow mine,” offered Karyn. “I want to see if it works anyway. And then we can brainstorm that Amazin order together if I can use your computer.”
Karyn removed her bra, without—to Jon’s chagrin—taking off her shirt, a feat akin to magic as far as he understood, and handed it to Jon.
Jon stood still for a moment, suddenly embarrassed, until Zoe whined, “C’mon, Jon! You know Mom said you have to use your swaps to help the family!” as Zoe also performed a magic bra removal and set it on Jon’s bed.
Awkwardly, Jon took both bras into the bathroom to “change”, but a minute later he returned—blushing and defeated he begged, “Can…can you help me do this up in the back?” Karyn and Zoe burst into a fit of giggles. “It’s ok, Jon. You’ll get the hang of it with more practice,” Karyn smirked. Jon reddened further as Karyn deftly turned the bra around backwards, showing him how to clasp it in front.
As Jon slid it back into place and pulled the straps back up over his arms, Karyn’s enhanced bust quickly deflated down to Zoe’s old A-cups as Jon’s chest ballooned with Karyn’s big boobs. Jon then donned the bra Zoe had gotten at the mall, his chest blossoming even further as Zoe’s shrank to Karyn’s only slightly smaller size.
“But your wish?” whispered Jon. “How?”
“I still have big boobs Jon—I’m just letting someone else borrow them. I’m not going against the original wish.” Karyn replied.
“Now,” she continued louder, “let’s do some shopping.” Zoe’s laptop was already open and she was already scrolling through the clothing selections. After a few minutes of Zoe and Karyn excitedly pointing and clicking, Karyn turned back to Jon:
“Were you going to finish changing, Jon…girl?” Jon glanced down. How had he forgotten about the F-cups dangling from his chest as he leaned over the back of the computer chair? Bashfully, he removed the bra and pulled on one of his T-shirts, returning to whatever passed for normal around here now.
“Zoe, why don’t you finish up in the other room? I need to talk to Jon for a minute. Just use the card on file for my account when you’re done. I have plenty of spending money saved up from my job.”
“Hey! Don’t I get to help with the order!” protested Jon.
“My money, my rules,” declared Karyn. “And Zoe there seems to be pointed in the right direction. Besides, you’ve never had any fashion sense. You would probably just buy something to give you a bigger dick.”
Zoe snickered and waved sarcastically on her way out the door. Jon didn’t know what to think of this new partnership between his best friend and his sister, but it probably wasn’t going to be good for him.
“Now, I need you to swap some things for me…”
